IMPROVEMENT IN MACHINES FOR POLISHING THE EYES 0F NEEDLES.

Specification forming part of Letters Patent No. 212,455, dated February18, 1879 application filed December 29, 1877.

The invention relates to the method of pol ishing the eyes'of needles,exemplified in the machine, of which- Figure l is 'a perspective Viewcomplete,

and Figs. 2, 3, 4, 5, and 6 are details of the same.

Its construction and operation are as follows:

A is the bed of the machine; B B, the uprights which support thedifi'erent parts of the mechanism. G is the thread-clamp, containing thethreads for polishing the needles. C is the needle-clamp, for holdingthe needles. F is a bridge, resting onthe two uprights B B, the objectof which is to support the threadclainp G, in the following manner:

The thread-clamp G is provided with the uprights m m and lugs n n, whichrest on the perpendicular bar cl, sliding in the bridge F, controlledand operated by the cam c and handle f, for raising and lowering thethread-clamp as required. The uprights m m are fastened to thehorizontal bar 6 by the buttons h h. The lugs it of the needle clamp 0pass through the horizontal slot q q in the uprights B B, and areconnected with the sliding bars I) b. On the outside of the sliding barsI) b are fastened the crank-plates 0 0, which are also connected withthe lugs 17 t of the needle-clamp 0, controlling and operating it.Motion is communicated to the sliding bars I) b by the connecting-rods aa from the driving-wheels E E. On the lower end of the crank-plates 0 0is the rolls t 6, which travel in the slots jj of the plates D D, ivingdirection to the needle clamp C. The slots j j are in reality cams.11gb]? plates D D are secured to the uprights Fig. 5 shows more clearlythe arrangement and construction of the needle-clamp with the slidingbars I) b and crank-plates 0 0.

The patent issued to Payne and George, July 10, 187 7, N 0. 193,031, wasfor the oscillatingthread-clamp, controlled and operated by hand, whilethis machine is automatical.

The former machine was so arranged that the emery had free access whichsoon cut them out.

The present machine has all the bearingpoints far removed from anypossible contact with emery.

The flat places 1 1 in the cam-slotsjj give the needle-clamp Csufficient stand-still at its highest point to polish and round thecorners of the eye, where most of the polishing is required. 1

The thread-clamp G, Fig. 2, is constructed with bars K K and rods 4" r,on which and between the bars K K are placed the washers Z Z Z I, &c.,one of which is shown at Fig. 4; and between the washers Z Z l l, 850.,are placed the polishing-threads, and they are held there firm and tautby the nuts 8 s on the rods 1' r. The uprights m m, with the lugs n n,are for to the bearings,

-the purpose of attaching the thread-clamp to the machine.

What we claim isl. The combination of the needle-clamp C, bars K K, rods7* r, washers l Z Z l, &c., uprights m m, lugs 11. n, with thehorizontal and perpendicular bars 0 and cl, cam c, handle f, buttons hh, as described, and for the purpose set forth.

2. The combination, with needle-clamp C, of the lugs 15 t, sliding barsI) b, crank-plates 0 0, rolls z 0', slots jj, and plates D D,substantially as described and set forth.
